✦ Three-row cylindrical roller configuration – Two axial rows (upper/lower) and one radial row, each with cylindrical rollers arranged in a triangular layout for balanced load distribution.

✦ Internal gear on inner ring – Gear teeth are integrally hobbed on the inner ring bore, featuring a 20° pressure angle spur profile with induction-hardened flanks.

✦ Monobloc outer ring – The outer ring is manufactured as a single-piece forging, incorporating both axial raceways and a central guide rib for radial rollers.

✦ Independent axial raceways – Upper and lower axial raceways are machined directly into the inner ring, providing separate load paths for each axial direction.

✦ Induction-hardened contact surfaces – All raceways hardened to 58–62 HRC with a case depth of 3.5–4.5 mm, while gear teeth are hardened to 50–55 HRC.

✦ Optimizes load paths – The triangular roller arrangement directs forces through the shortest possible path, minimizing structural stress on surrounding components.

✦ Improves gear protection – Internal gear placement shields teeth from external impacts, reducing the risk of tooth damage during operation.

✦ Enables compact drivetrains – The internal gear allows the drive pinion to be placed within the bearing cavity, reducing overall machine width.

✦ Simplifies sealing – The enclosed design reduces the number of exposed sealing surfaces, improving overall sealing reliability.

✦ Enhances safety – The internal gear eliminates exposed pinch points, improving operator safety in manual maintenance areas.

✦ Extends gear life – The enclosed gear cavity provides better lubricant retention, ensuring consistent lubrication of gear teeth.
